Travel eSIM top-ups: extra data, days or a new plan?

• A compatible priced offer: read the allowance, validity effect and total before continuing to payment. The offer must belong to your existing eSIM.
• Ask about more data: this requests an eligibility check. It is not a completed purchase, a guaranteed available top-up or confirmation that data has been added.
• Buy again: this is a new eSIM purchase, with its own setup and timing.
• No option: contact support about the exact order. Availability cannot be inferred from another customer’s plan or the current destination catalogue.

Sign in to My Account and choose My eSIMs. Match the entry to the traveller and phone using it. If you cannot access the order there, keep your original order email available and contact us. Do not share account passwords to let a companion use the controls.

Check the remaining-data reading and its checked time. A stale figure is not a reason to buy twice. If a payment or top-up is already pending, follow its status before placing another order.

Suppose you have data left but the trip runs beyond the plan’s expiry. More gigabytes alone may not solve that problem. Conversely, extra days do not necessarily refill a daily high-speed allowance that has already been used.

Before paying, identify the new expiry and how much data will be added. If either is missing, send us the order number and a screenshot of that offer, with private details hidden, and wait for the answer. Do not assume a top-up restarts a finished plan, restores full speed immediately or changes country coverage. Our validity guide separates these clocks.

Keep the original eSIM installed. A payment confirmation doesn’t yet confirm that the extra data has reached it, so check the order or account status before trying to buy again. Refresh the balance where that option is available; usage reporting can take time to catch up.

If the result is unclear, send the order number, the affected eSIM’s non-sensitive reference, what you bought and the status you can see. Do not send QR or activation details, and do not delete the current profile.

A replacement purchase can be appropriate when the old plan is finished or no compatible extra package is available. It is still a new installation. Follow its own instructions after landing on stable Wi-Fi, and check that you select the new line for data. Keep the old profile until its status and any open support issue are resolved.
